NASCAR sets date for spoiler switch
CONCORD, N.C. -- The spoiler officially will replace the wing on Sprint Cup cars for the March 28 race at Martinsville Speedway, NASCAR vice president of competition Robin Pemberton said Wednesday.
The process of shipping spoilers to all the teams began on Monday.
"We feel it should go fairly smooth," Pemberton said.
NASCAR has targeted Martinsville for months, believing it will be best to start with the spoiler at a short track where aerodynamics won't be a major factor. The spoiler has been used at intermediate tracks such as Texas and Darlington during tire tests with no complications.
"It ran better and had a little more downforce," Pemberton said.
A full test with all teams is scheduled for Tuesday and Wednesday at Charlotte Motor Speedway. Officials were pleased with the results from a 24-team test at Talladega Superspeedway on Tuesday.
Pemberton said a standard four-inch high spoiler will be used at all short tracks and intermediate tracks. The height and width of superspeedway spoilers has not been finalized for Talladega and Daytona.
